Abstract

A diaphragm control valve provides substantially straight-through fluid flow, which enables a high-flow capacity with minimal pressure loss. The non-planar diaphragm (200) when standing in a non-stressed state, is substantially an annulus that assumes a shape with a cross section that extends from a first attachment bead (220) substantially radially in a first direction through a first curve (210) continues substantially non-radially in a second direction through a second curve (212) and continues in a substantially radial direction terminating in a second attachment bead (228), such that the diaphragm does not fold back upon itself. The diaphragm (200) is both axially non-overlapping and rotationally symmetrical.
